Tadalafil Impurity 169 CAS CATO-C4X-1087169

Description

The occurrence of Tadalafil Impurity 169 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Tadalafil Impurity 169 (CAS CATO-C4X-1087169), a pharmacopoeial impurity reference standard (molecular formula C16H27N3O, MW 277.41 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C16H27N3O, Tadalafil Impurity 169 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 277.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Tadalafil Impurity 169 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
